Description

Technical Field

[0001] The utility model relates to the technical field of indoor decoration, in particular to a rapid ventilation device for indoor decoration of buildings. Background Art

[0002] During interior decoration, more dust, paint smell and other irritating odors will be generated, so it is necessary to open windows for ventilation to make the indoor air fresh. However, if you rely solely on natural ventilation, the ventilation efficiency is low. When the wind force is low, ventilation takes a long time. Some ventilation devices are equipped with exhaust fans, which are installed at one of the windows. When the exhaust fan is turned on, the indoor air is blown out of the window to the outside, and the outdoor air is supplemented into the room through the remaining windows, so that a larger airflow is formed indoors, improving ventilation efficiency.

[0003] However, existing ventilation devices are generally not equipped with filtering devices, resulting in a lot of dust on the fan blades of the exhaust fan. A large amount of dust is directly discharged into the outside air and may fall onto the windows of the residents on the lower floors, affecting the living experience of the residents on the lower floors.
